Maybe socks imprinted with Big Macs. Or a French fry bandana. Or a T-shirt, jeans jacket or enamel pin from the Throwback Collection.

It’s the second annual Global McDelivery Day. Most of the giveaways are 1990s-inspired items (the retro fanny pack comes emblazoned with burgers) except, of course, for the PopSocket, which customers never dreamed they’d need two decades ago.

The swag went fast on the inaugural McDelivery Day last year, with the coveted “Big Mac Onesie” leading the list.

Here’s how this year’s giveaway will work: Place an online Uber Eats order starting at 10:30 or 11 a.m. at a participating McDonald’s (depending on when the lunch menu kicks in). A minimum $5 order is required. Then wait to see which piece of themed merchandise arrives. Uber drivers will add a freebie to your order, while supplies last.
